Bushnell 788876 Telescope Specification

The Bushnell 788876 Telescope is designed for astronomy enthusiasts seeking a blend of performance and portability. Featuring a 700mm focal length and a 3-inch aperture, this refractor telescope provides clear and detailed views of celestial bodies. Its fully coated optics enhance light transmission, delivering bright and sharp images of the moon, planets, and other astronomical objects. The telescope is mounted on a sturdy altazimuth mount that allows smooth and precise tracking of objects across the night sky. A slow-motion control feature enhances the user's ability to make fine adjustments when observing celestial phenomena. Included with the telescope are interchangeable eyepieces that offer varied magnification options, enabling users to customize their viewing experience according to their interests and observational targets. The Bushnell 788876 is also equipped with a 3x Barlow lens, effectively tripling the magnification range of the eyepieces for more detailed observations. A red dot finderscope simplifies the process of locating objects and aligning the telescope. Designed with user convenience in mind, the telescope is lightweight and comes with a tripod that can be easily assembled and disassembled, making it highly portable for outdoor stargazing sessions. Its compact design ensures easy storage and transportation, catering to both amateur astronomers and seasoned stargazers. The Bushnell 788876 Telescope stands as a reliable entry-level option, combining quality optics with user-friendly features to facilitate a rewarding astronomical exploration experience.

Bushnell 788876 Telescope F.A.Q.

How do I align the Bushnell 788876 Telescope properly?

To align your Bushnell 788876 Telescope, first set it up on a stable surface. Use the finderscope to locate a bright object in the sky. Then, adjust the telescope's position using the slow-motion controls to center the object in the eyepiece.

What is the best way to clean the lenses of the telescope?

Use a soft, lint-free cloth to gently wipe the lenses. For stubborn spots, use a lens cleaning solution specifically designed for optics. Avoid using household cleaners or rough materials that might scratch the lenses.

My telescope's view is blurry; what should I check?

Ensure that the eyepiece is securely inserted, and check that the lens is clean. Verify that the telescope is focused properly by adjusting the focus knob. Additionally, make sure the telescope is at thermal equilibrium; allow it to adjust to the outside temperature.

How can I stabilize my telescope during windy conditions?

To stabilize your telescope, you can add weight to the tripod base, such as a sandbag. Additionally, try setting up the telescope in a sheltered area to minimize wind impact.

What should I do if the telescope's mount is difficult to move?

Check if the mount's locking knobs are too tight. Loosen them slightly to allow for smoother movement. If the issue persists, inspect the mount for any debris or damage and clean or repair as necessary.

How often should I perform maintenance on my Bushnell 788876 Telescope?

Regular maintenance should be performed every few months, depending on usage. This includes cleaning the lenses, checking for loose screws, and ensuring the mount moves smoothly.

Can I use my Bushnell 788876 Telescope for astrophotography?

Yes, the Bushnell 788876 Telescope can be used for basic astrophotography. You will need a compatible camera adapter to attach your camera to the telescope. It's essential to have a sturdy tripod and possibly a tracking mount for long-exposure shots.

What is the maximum magnification I can achieve with this telescope?

The maximum useful magnification of the Bushnell 788876 is about 50 times the aperture in inches. However, exceeding the recommended magnification can result in blurry images due to atmospheric conditions and optical limitations.

How can I improve image clarity during observations?

Ensure the telescope is properly focused and the lenses are clean. Observing from a location with minimal light pollution and when the atmosphere is stable (e.g., not too windy) can also improve image clarity.

What should I do if the telescope's image is inverted?

Inverted images are normal with astronomical telescopes. You can use an erecting prism to correct the image orientation if you plan to use the telescope for terrestrial viewing.
